'V1' alarm
acknowledge-
ment time
·
This is a countdown which is active for automatic fire detectors when the system is in
'Manned' operating mode.
·
Checks whether anyone has acknowledged the danger alarm within a pre-programmed time.
·
But if this time passes without acknowledgement, the alarm is transmitted to the fire brigade.
·
The time remaining is shown on the display in minutes and seconds.
'V2' alarm inves-
tigation time
·
This is a countdown which is active for automatic fire detectors when the system is in
'Manned' operating mode.
·
Limits the time for investigating the fire location to an individually pre-programmed period.
·
But if this time passes without resetting, the alarm is transmitted to the fire brigade.
·
The time remaining is shown on the display in minutes and seconds.
·
In the event of minor incidents, the alarm must be reset before V2 expires to prevent an un-
wanted remote alarm transmission.
